iOS 6强制定位

Question

在iOS5中,您可以使用此代码段强制方向:

UIViewController *c = [[UIViewController alloc]init];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
[c release];

但是这会在iOS6中导致EXC_BAD_ACCESS.如何在iOS6中强制某个方向？

Answer 1

只是为了完成上一个答案,你应该这样做:

UIViewController *viewController = [[UIViewController alloc] init];
[self presentViewController:viewController animated:NO completion:^{
    [viewController dismissModalViewControllerAnimated:NO];
}];

而且iOS 6不再是NDA.

Answer 2

如果有人仍然关心这一点，这里是 iOS6 代码片段（我将其放在 viewDidLoad 例程中）：

UIViewController *viewController    = [[UIViewController alloc] init];
viewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:viewController animated:NO completion:^{
    [self dismissViewControllerAnimated:NO completion:nil];
}];
